Just catching up, with street names, the one that interests me is Cross's claim in the Morning Advertiser,
"I went down Parson street, crossed Brady street, and through Buck's row."
No Parson in the area, ever, as far as I can tell.
Closest is Pereira Street, next to Foster. It was called Park Street, Park Street/ Parson could be a mishearing.
What intrigues me is the term, "I went down", On the map Pereira would be consistant with "down", but, of course, "down" can mean along! I've checked if Cross describes going "down" Buck's Row, he doesn't.
So, all in all I'm wondering if he did, in fact, go down Pereira?
